GlassPlayer v0.9.0

by Fred Gleason

On behalf of the Rivendell audio community, I’m pleased to announce the initial beta release of GlassPlayer, a minimalist live audio player. that is available under the GNU Public License v2. From the README file: *** snip snip *** GlassPlayer is a minimalist audio stream player for IceCast and Shoutcast streaming servers as well as HLS streams. It supports the following audio output types: Advanced Linux Sound Architeture (ALSA) File Streaming (FILE) JACK Audio Connection Kit (JACK) Standard Output (STDOUT) Windows Multimedia Extensions (MME) The base GlassPlayer component utilizes no configuration files or GUI interface whatsoever; with the 'user interface' consisting entirely of the command-line invocation. As such, it is well suited for use cases where the player is completely driven by an external system or script. The following audio codecs are supported: OggOpus OggVorbis MPEG-1/2 Layer 2 ('MP2') MPEG-1/2 Layer 3 ('MP3') MPEG-4 Advanced Audio Coding, High Efficiency Profile ('HE-AAC+') *** snip snip *** Further information, including full source code, is available at https://github.com/RadioFreeAsia/GlassPlayer.

Ninjas2 sample slicer plugin released (v.0.2.0)

by Rob van den Berg

Hi all, I've updated Ninjas2 audio sample slicer plugin. Source and binaries (linux/windows/mac) are available at : https://github.com/rghvdberg/ninjas2/releases/tag/v0.2.0 readme : https://github.com/rghvdberg/ninjas2/blob/master/README.md >From the readme: #Goal: Easy to use sample slicer, quick slicing of sample and auto-mapping slices to midi note numbers. # Intended usage: Primarily targeted at chopping up loops or short ( ≈ 10 - 20 seconds) samples. Think drum loops, vocal chops etc. Currently there's no limit on imported sample length. User can play the slices using midi notes and change the pitch with midi pitchbend. # Downloads: Linux, Windows and Mac binaries for several architectures are available here. There are no installers, just unzip and copy the plugin to an appropiate location. # New Features - redesigned interface - controls are grouped in Global, Slicing and Slice - the Slice box shows the currently selected slice number - keyboard - click on key to play slice - red dot on key indicates which slice is currently selected in the waveform display - keys that don't have a slice mapped to them are greyed out # Known Bugs and Limitations - some host don't work very well with the lv2 version - zrythm and qtractor had trouble with the lv2 version but worked fine with the vst - ardour, carla and muse3 worked well with the lv2 - care should be taken when automating the playmodes and adsr - the automation is sent to the currently played note (slice), when multiple slices are played, this leads to "undefinied behaviour"

Signal Estimator

by Victor Gaydov

Hi, signal-estimator is a small command-line tool allowing to measure latency and loss ratio of the signal looped back (somehow) from ALSA output device to ALSA input device. I created it to measure the total latency of an Android phone with a Bluetooth headset. Link: https://github.com/gavv/signal-estimator/ -- Victor

Zrythm 0.7.367 release

by Alexandros Theodotou

Zrythm 0.7.367 has been released! ################################# Screenshot: <https://www.zrythm.org/static/images/jan-14-2020.png> Installer (paid): <https://www.zrythm.org/en/download.html> Source tarball: <https://www.zrythm.org/releases/zrythm-0.7.367.tar.xz> Signature: <https://www.zrythm.org/releases/zrythm-0.7.367.tar.xz.asc> SHA256 sum: < https://www.zrythm.org/releases/zrythm-0.7.367.tar.xz.sha256sum> # What is Zrythm Zrythm is a digital audio workstation designed to be featureful and easy to use. It allows limitless automation, supports LV2 plugins, works with the JACK audio backend, provides chord assistance, is free software and can be used in English, French, Portuguese, Japanese and German. It is written in C using the GTK+3 toolkit. More info can be found at <https://www.zrythm.org> # Current state We believe that Zrythm is now in the late alpha stage where most essential features are implemented and it's starting to be more stable, and we are approaching beta. It seems to be usable for MIDI-based workflows and the UI is very responsive on well-tuned machines. The main changes since the last announcement are the following (you can view the whole changelog here: < https://github.com/zrythm/zrythm/blob/master/CHANGELOG.md>;). ## Optimized UI The drawing code for many parts of the interface has been rewritten with optimization in mind. We saw big improvements in performance and CPU usage, so if you tried Zrythm before and your CPU usage was going crazy, or if it was laggy on your machine, we highly suggest you give the new release a spin. More specifically, the following were composite GTK widgets before, which was causing too many calculations to be done and lag when too many objects were on the screen - something not acceptable for a DAW. We converted them into canvases, which means that everything inside these gets drawn in one go, avoiding the need for multi-step, nested calculations. - Tracks - Timeline arranger - All editors (piano roll, chord editor, automation editor, audio editor) - Piano roll keys ## Experimental VST support We added support for Linux VSTs. ## Many, many bugfixes You will find that Zrythm is much more stable now. If you spot any bugs/crashes, PLEASE report them. We want to fix all of them. ## More distros supported Debian 9 (stretch) and all derivatives (Ubuntu 18.04, AVLinux, LinuxMint 19.3, LibraZik 2, etc.) are now supported. Many people were having problems installing supported versions of some dependencies, such as lilv. Zrythm can now automatically fetch and build these dependencies as a fallback if they are not found, thanks to meson's wrap system. ## New logo Thanks to Carlos Han - C.K. Design (<https://twitter.com/karl_iaxd>) for the new logo! # Next on the TODO list Our next goal is to support Windows. After that, we will work on stability and fixing any bugs and crashes so we can get Zrythm into beta, so please help us find them. # Links Home page: <https://www.zrythm.org> Git repositories: <https://git.zrythm.org/cgit/> Manual: <https://manual.zrythm.org/en/index.html> Developer reference: <https://docs.zrythm.org/> Bug reports: <https://redmine.zrythm.org/projects/zrythm/issues> Releases: <https://www.zrythm.org/releases/>
